-(w+0.2)=0.3(4-3)

Solution for -(w+0.2)=0.3(4-3) equation:

Simplifying
-1(w + 0.2) = 0.3(4 + -3)

Reorder the terms:
-1(0.2 + w) = 0.3(4 + -3)
(0.2 * -1 + w * -1) = 0.3(4 + -3)
(-0.2 + -1w) = 0.3(4 + -3)

Combine like terms: 4 + -3 = 1
-0.2 + -1w = 0.3(1)

Multiply 0.3 * 1
-0.2 + -1w = 0.3

Solving
-0.2 + -1w = 0.3

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '0.2' to each side of the equation.
-0.2 + 0.2 + -1w = 0.3 + 0.2

Combine like terms: -0.2 + 0.2 = 0.0
0.0 + -1w = 0.3 + 0.2
-1w = 0.3 + 0.2

Combine like terms: 0.3 + 0.2 = 0.5
-1w = 0.5

Divide each side by '-1'.
w = -0.5

Simplifying
w = -0.5
